How to use glob file specifications for stylus on the command line? - command-line

Question

I have many directories. In many of those there is a .styl file. I want to create a .css file within that same directory for each directory containing a .styl file. Additionally, whenever the .styl file is updated, I'd like the respective .css file to update.
I'm trying to create a script in my package.json to accomplish this, but without much luck. I don't know how to specify an output filename dynamically either, so I realize that part of the code bellow is incorrect. Before tackling that (potentially) I have an error I'll describe after the code. I'm open to an alternative output, I just want my .styl files to stay in their modules and whatever .css file(s) that are output to update automatically.
Here's the relevant commands from the "scripts" part of my package.json:
"styles": "stylus -u autoprefixer-stylus ./src/**/*.styl -o ./src/css/",
"styles:watch": "stylus -u autoprefixer-stylus -w ./src/**/*.styl -o ./src/css/",
"watch": "concurrently --names 'webpack, stylus' --prefix name 'npm run start' 'npm run styles:watch'"
Here's the error:
[ stylus] > stylus -u autoprefixer-stylus -w ./src/**/*.styl -o ./src/css/
[ stylus]
[ stylus] /Users/itsme/Projects/todo-react/node_modules/stylus/bin/stylus:641
[ stylus] if (err) throw err;
[ stylus] ^
[ stylus]
[ stylus] Error: ENOENT: no such file or directory, stat './src/**/*.styl'
Full package.json if it's helpful:
